REPLACING THE
BATTERY
If you follow the instructions in “Con-
necting and Charging the Battery” on
Page 10, the battery should last about
one year. If the battery will not hold a
charge for more than 2 hours after an
overnight charge, replace the battery
with a new 3.6 V, 300 mAh battery with
a connector that fits the socket in the
battery compartment. You can order a
replacement battery through your local
RadioShack store.
Install the new battery as described
below, then charge the battery for
about 14 hours before you use the
handset.
Note: To avoid losing phone numbers
stored in the handset’s memory, try to
install and begin charging the new
battery within 1 minute after removing
the old one.
1. Using a Phillips screwdriver,
remove the screw on the battery
compartment cover on the bottom
of the handset. Then press down
and slide off the cover in the direc-
tion of the arrow.
2. Gently pull on the battery connec-
tor to disconnect it, then remove
the battery.
3. Insert a fresh battery and insert its
connector into the socket inside
the battery compartment.
4. Replace the cover and tighten the
screw.
Caution: You must use a replacement
battery of the same size and type.
Important: This product contains a re-
chargeable nickel cadmium battery. At
the end of the battery’s useful life, it
must be recycled or disposed of proper-
ly. Contact your local, county, or state
hazardous waste management authori-
ties for information on recycling or dis-
posal programs in your area. Some
options that might be available are: mu-
nicipal curb-side collection, drop-off box-
es at retailers such as your local
RadioShack store, recycling collection
centers, and mail-back programs.
